Description

  The present invention relates to a furniture with a top plate and an auxiliary top plate that can provide a manager seat with almost no change in the basic layout even if the worker's seat position, number of people, etc. are changed according to the work form of the worker. Is.

There is known an office layout in which a plurality of desks each having a plurality of desks arranged in opposed islands are arranged on the floor at appropriate intervals to form a plurality of islands. In the case of such an office layout, the manager's desk is generally arranged with the counter-use edge at the side edge of the opposing island type desk group used by ordinary workers. is there. (For example, see Non-Patent Document 1)
Recently, instead of arranging a plurality of desks as opposed islands, a large table type desk with a relatively long left and right width may be used as one island. As such a large table type desk, there is also considered one that can change the layout according to the work of a worker such as a project, a meeting, or a computer work. (For example, see Patent Document 2)

  However, even with this configuration, when a manager's seat is to be provided, the manager's desk's depth dimension is equal to that of other islands, as in the case of arranging a plurality of desks on opposite islands. There is a problem that the balance of the entire office space becomes worse. In addition, depending on the floor shape of the office, the position where the manager seat is provided may be limited, and the layout pattern is limited. In addition, there is a problem that a manager desk must be prepared and the desk must be moved each time the layout is changed. In particular, in the recent office environment, it is required that the layout corresponding to each worker's work as described above can be easily changed while minimizing various costs such as construction and cost. Our furniture did not fully meet this requirement.

  Therefore, in view of the above problems, the present invention provides a furniture with a top plate and an auxiliary top plate that can provide a manager seat flexibly without changing the basic layout even when a change occurs in the office working environment. Is to provide.

  That is, the furniture with a top plate of the present invention is composed of a top plate that uses the front and rear edges as a working edge and a support structure that supports the top plate, and the top plate is a counter-use edge of a plurality of top plate elements. It is formed by jointly arranging each other, further comprising an auxiliary top plate placed on the upper side surface of the top plate, and this auxiliary top plate is a longitudinal dimension of the top plate. A planar covering portion having a width substantially corresponding to the above and a positioning means for the top plate.

  Further, the auxiliary top plate includes a top plate using the front and rear edges as a working edge and a support structure that supports the top plate, and the top plate is arranged so that counter-use edges of a plurality of top plate elements are opposed to each other. The sheet cover is placed on the upper surface of the side of the furniture main body with a top plate, and has a width substantially corresponding to the front and rear dimensions of the top plate and movement with respect to the top plate. And a positioning portion to be regulated.

  In such a case, a manager seat can be easily provided by simply superimposing an auxiliary top plate having a work area for a user (manager, etc.) from the side end side on the upper surface of the side end portion of the furniture with the top plate. I can do it. That is, since the joint produced by arranging the edges of the top plate elements to face each other is concealed, the side region of the furniture with the top plate can be used as the work area of the manager. Therefore, there is no need to add a new manager desk or top board to the side edge of the island, and the total length of one island is almost the same, with or without a manager seat. Even so, the overall balance of the office space will not be compromised.

  Further, in order to stably superimpose the auxiliary top plate on the top plate, the positioning means can be engaged with the front and rear edges of the top plate on a part of the surface covering portion of the auxiliary top plate. It is desirable to provide a folded portion as a positioning portion and to engage the folded portion with the front and rear edges of the top plate.

  Further, in the case where the joint is formed from a gap having a predetermined width, a protrusion that is a positioning portion that substantially corresponds to the width dimension of the gap is provided on the back surface side of the auxiliary top plate, and this protrusion is disposed in the gap. The positioning means may be configured by being inserted into the.

  If the projecting portion is constituted by a channel-shaped reinforcing portion having a length substantially corresponding to the depth dimension of the auxiliary top plate, the thickness of the auxiliary top plate can be reduced, and the region where the auxiliary top plate is provided. And other areas can be suppressed.

  The support structure is composed of a plurality of legs that support both sides of the top plate and a horizontal frame that connects the upper portions of the legs, and the top plate is located on one side. Provided with an extending portion that projects outward from the leg, and the auxiliary top plate is placed on the upper surface of the extending portion, the leg is positioned inward from the side end of the top plate. Therefore, the interference between the manager's legs and the legs of the furniture with the top plate can be reduced, and the lower limb space of the manager can be effectively secured.

  In this case, the extension portion can be stably supported by providing an auxiliary support body that supports the extension portion from below.

  Specifically, it is desirable that the auxiliary support body includes a pair of auxiliary legs that support at least the front and rear of one side end side of the extension part, and more specifically, the auxiliary support body includes the extension part. From a pair of auxiliary legs that support the front and rear of one side end side, an auxiliary connecting part that connects the upper ends of the auxiliary legs, and a horizontal connecting part that connects the auxiliary connecting part and the leg located on the one side part side The thing which becomes. With such a configuration, the strength of the entire furniture with a top plate can be obtained, and both the connecting portions can be used as attachment portions for options such as a tray under the top plate for a manager and a desktop panel. In particular, in the type of furniture with a top plate that can be extended in the longitudinal direction, the auxiliary support body can be attached using the additional points, which is more effective.

  According to the present invention, even when a manager's seat is to be provided on the side edge of the island, work can be performed without newly providing a manager's desk or top plate on the side edge of the island. A manager's seat can be easily provided only by superposing the auxiliary top plate having the area on the upper surface of the side end portion of the furniture with the top plate. That is, since the total length of one island is almost the same between the case where the manager seat is provided and the case where the manager seat is not provided, the layout can be changed according to the work of the worker without losing the layout balance of the entire office space.
